Ionizing radiation

fatal to nearly all other known life forms, such as exposure to extreme temperatures, extreme pressures, air deprivation, radiation, dehydration, and starvation. Water bears can withstand extremely cold temperatures down to 1 Kelvin or −458 °F, hot temperatures up to 420 Fahrenheit, pressures of about six times greater than those found in the deepest ocean trenches, ionizing radiation at doses hundreds of times higher than the lethal dose for a human, and the vacuum of outer…

Leukemia is a cancer of the blood, the complex disease occurs when there is too many white blood cells present or cancer cells are in the bone marrow. Leukemia is a Greek word that is broken down into leuko which means white and haima meaning blood. Peter Cullen found incomprehensibly what was called “milky blood” early in 1811. In 1825, Alfred Velpeau discovered the symptoms of Leukemia and found pus in the blood of patients. During the 19th century, the disease was first named weisses blut…

1. Personal Hygiene: “Hand Washing, fingernails, food worker illness policy (including exclusion of ill workers, cuts, burns, bandages, etc.), hair, uniforms, glove use, jewelry, personal cleanliness, or unsanitary habits such as eating, drinking, smoking, or spitting are all parts of defining personal hygiene standards.” Poorly handwashing is one of the leading causes of foodborne illness. 2. Time and Temperature Control of Foods: “Able to reduce bacterial growth in potentially hazardous foods…

Introduction: Head trauma is considered as a common complaint in Emergency Department (ED). Each year, 1.7 million patients are referred to US EDs due to the head trauma [1], which most of them are diagnosed as minor head injury. Although minor head injury is common in Iran, but unfortunately the exact number is unknown. Minor head injury has been defined as Glasgow Coma Scale (GCS) 13-15 [2-4] or GCS equals 14 and 15 [5]. Computed Tomography (CT) is a standard imaging for acute head injury.…

Nearly all ancient societies practiced body modification through either piercingss or tattoos. These ancient practices are becoming ever more present in our modern Canadian society, especially tattoos. One writer says, “Permanent tattooing is the process of body modification by deposition of a pigment into the dermis” (Simunovic and Shinohara 525). In the past three decades, magnetic resonance imaging (MRI) has become increasingly popular in the medical field. Magnetic resonance imaging is a…

This is because the type of energy being used in the scanner is an ionizing radiation that breaks chemical bonds. a study shows that, “If 1 million people were exposed to 520 scans in one year,there is an estimate that roughly four additional cancers would occur due to the scanner, in contrast to the 600 additional cancers that would occur from the higher levels of radiation during flight.” When a source took a vote on whether the backscatter X-Ray was a positive or negative…

about the issue of cell phone radiation and how people interact with them, helped to show the significance of the issue. People had no form of really understanding the problem and do not even know the regulations, manufacturers have on the contact customers should have with a phone. For some people it is out of reach this information, there is ambiguity about what a cell phone can do to their health. From the research found people were unaware of the level of radiation they are exposed to and…

trial to evaluate the benefit of adding zalutumumab to radiotherapy. In this trial, 619 patients with SCCHN (89%with stage III-IV disease) were randomized to receive radiation (n=309) or radiation plus zalutumumab at 8 mg/kg (n=310). Zalutumumab was started one week prior to beginning radiation and continued weekly during radiation. The first results showed that the two arms did not show any difference in LRC (79% vs. 78%). Although patients with p16 positive tumors had better LRC (83% vs. 73%…

Cells are the basic building block of life, it plays a vital role in transferring human language called DNA from generation to generation. DNA stands for Deoxyribose Nucleic Acids, it contains genetic information for our cells. It contains all the essential elements of the universe, in such precise quantity, that it sustains life. Our DNA, is able to instruct the cell in terms of which protein they have to make.Following the instructions, the protein created determines the cell…
